Developer D10 Chambers Collective has released a new video detailing the so-called Rundown system of GTFO, their upcoming hardcore co-op FPS with a survival horror twist. Essentially, a Rundown, given out by the mysterious Warden, consists of a series of tasks to be carried out in a dangerous underground complex teeming with monsters – what’s more, these expeditions have to be completed within a certain time limit. Once the allotted time runs out, a new Rundown takes the old one’s place, containing a set of new tasks. Depending on the number of tasks and how deep you venture into the complex, a single Rundown could last weeks or even months before the next one shows up. The developers have also added that they’re planning for each Rundown to offer a specific experience in order to keep things fresh and interesting.
